Merit Abrasives 63642505650 Quick-change Disc 2in 80 Grit

Product Description

The MERIT ABRASIVES 63642505650 is a 2-inch quick-change abrasive disc designed for use with Roloc TR-style (Type R) attachment systems. It features an aluminum oxide abrasive on a cloth backing with an X-weight backing material, rated for up to 30,000 RPM. At 80 grit, it falls in the medium grade range, making it well-suited for aggressive surface preparation, weld blending, and deburring on metal surfaces. The brown coated disc mounts quickly without tools, allowing fast disc changes during production grinding and finishing work. Installation and use are handled by metalworkers, fabricators, and maintenance technicians working with angle grinders and die grinders.

This disc is intended for use on metal fabrication, maintenance, and repair applications where consistent stock removal at medium grit is required. Typical scenarios include weld seam blending, light rust removal, surface conditioning before coating, and edge deburring on ferrous and non-ferrous metals. The Type R quick-change attachment is a widely used standard in industrial and trade grinding applications. Sold individually, with a minimum order quantity of 25 units.

Installation Notes

Mounting is performed by pressing the disc onto a Type R quick-change mandrel until it locks into place.

Inspect the disc for damage before each use and discard any disc that shows signs of cracking, tearing, or excessive wear.
